FIELD

The present disclosure relates generally to a cargo pallet, and moreparticularly, to a cargo pallet having a pallet extension. Thedisclosure also includes cargo pallets in which the pallet extension isin the form of a platform.

BACKGROUND

Shippers transport a significant amount of freight these days usingcargo aircraft or in the cargo holds of passenger aircraft. Because ofthe high costs associated with transporting cargo by air, shippers tryto arrange the cargo in the cargo hold so as to utilize as much of thevolume of the cargo hold of an aircraft as possible. Typically,individual packages of cargo are accommodated in a container, which isthen loaded into the cargo hold of the aircraft. Such containers, calledunit load devices (ULDs) are commonly used in the freight industry. SomeULDs are shaped to conform to the interior contours of a cargo hold.

The side and top walls of the ULDs, however, limit access to the innervolume of the ULDs during loading of the packages into the ULDs.Moreover, the side and top walls of the ULDs themselves occupy somevolume, which is not available for placing packages in the ULDs. Someshippers use cargo pallets instead of ULDs. Cargo pallets are typicallysquare or rectangular flat structures on which packages can be stacked.A cargo net is often used to cover the stacked packages. The net issecured to the sides of the pallet to ensure that the packages are notdislodged from the cargo pallet.

Shippers also sometimes employ a modified cargo pallet that has angledpanels extending from two edges of the cargo pallet. The angled panelsallow for additional space for stacking the packages making up thecargo. To ensure that the angled panels can support the weight of thepackages loaded on to the modified pallet, the angled panels aretypically connected to the base of the pallet, using support cables orother bars. These support cables or bars, however, are prone to severedamage during loading or movement of the pallet using, for example, afork lift vehicle or a crane. The support cables or bars also limitaccess to the base of the cargo pallet during placement of packages onthe cargo pallet, making it difficult to use all of the available spaceon the pallet.

The cargo pallet of the present disclosure represents an improvementover the prior art and solves one or more of the problems set forthabove and/or other problems of the prior art.

DETAILED DESCRIPTION

FIG. 1 illustrates a fragmentary view of an exemplary cargo hold 10. Inone exemplary embodiment as illustrated in FIG. 1, cargo hold 10 may bedisposed within an aircraft 12. Aircraft 12 may be a cargo aircraft, apassenger aircraft, a military transport aircraft, or any other type ofaircraft capable of transporting cargo. It is also contemplated that insome exemplary embodiments, cargo hold 10 may be disposed within a ship,on a vehicle capable of travelling on land, or in a cargo container,which may be transported by an aircraft, by a ship, and or by aland-based vehicle.

Cargo hold 10 may include a floor 14, a ceiling 16, side walls 18, andcontoured side walls 20, which may define a cargo volume 22. Floor 14may include loading equipment 24. In one exemplary embodiment, loadingequipment 24 may include rollers (not shown) that may help roll ULDs orcargo pallets into cargo volume 22. It is contemplated that loadingequipment may take the form of ramps, conveyor belts, rails, or othertype of loading mechanisms to help move cargo into cargo volume 22. Itis also contemplated that in some exemplary embodiments, floor 14 maynot include loading equipment 24.

Ceiling 16 may be disposed opposite floor 14. Side walls 18 may extendfrom ceiling 16 towards floor 14. In one exemplary embodiment asillustrated in FIG. 1, cargo hold 10 may have at least two side walls 18disposed spaced apart from each other. Side walls 18 may have a planaror curved shape. Contoured side walls 20 may extend from side walls 18to floor 14. In one exemplary embodiment, when cargo hold 10 is disposedin an aircraft 12, side walls 18 and contoured side walls 20 may have agenerally curved shape corresponding to the shape of an aircraft cabinor cargo bay.

FIG. 2 illustrates a perspective view of an exemplary disclosed cargopallet 30. As illustrated in FIG. 2, cargo pallet 30 may include palletbase 38, pallet liner 40, and one or more connectors 42. Pallet liner 40may be positioned on pallet base 38. Positioning pallet liner 40 onpallet base 38 may include placing pallet liner 40 on pallet base 38.Positioning pallet liner 40 on pallet base 38 may at least partiallydefine a space for receiving cargo. For example, pallet base 38 andpallet liner 40 may define a space in which one or more packages may bearranged for loading in cargo hold 10. Positioning pallet liner 40 onpallet base 38 may increase the available space in which a shipper maystack packages on cargo pallet 30. As shown in FIG. 2, pallet liner 40provides additional structural support on at least two sides of cargopallet 30 so that the packages may be stacked on top of each otherwithout the packages falling from or being dislodged from cargo pallet30. As explained in more detail below, after the packages are loadedonto cargo pallet 30, a cargo net may be placed over the load andattached to cargo pallet 30, before cargo pallet 30 and the load areplaced in cargo hold 10 for transporting cargo pallet 30 with the load.

As illustrated in FIG. 2, pallet liner 40 may be detachable (orremovable) from pallet base 38 and may be positioned directly onto thepallet base. As explained in more detail below, pallet liner 40 includesextensions that extend beyond the footprint of pallet base 38 andincrease the surface available to support the packages and/or othermaterials that may be loaded onto cargo pallet 30. Pallet liner 40 maybe detachably (or removably) connected to pallet base 38 via one or moreconnectors 42. It is contemplated, however, that in some exemplaryembodiments, pallet liner 40 may be fixedly attached to pallet base 38by, for example, riveting, welding, brazing, with an adhesive, or byother means of attachment. It is also contemplated that in someexemplary embodiments, pallet liner 40 may be positioned on pallet base38 without being fixedly or detachably connected to pallet base 38.

Pallet base 38 and pallet liner 40 have been illustrated in FIG. 2 ashaving generally rectangular shapes. In the embodiment shown, palletbase 38 and a base of pallet liner 40 may have the same general shapeand size, with the base of the pallet liner 40 fitting onto pallet base38, with the exterior portions of the pallet base 38 extending slightlybeyond the base of pallet liner 40. It is contemplated, however, thatpallet base 38 and pallet liner 40 may have any shape. It is alsocontemplated that a shape of pallet liner 40 may be the same as ordifferent from that of pallet base 38.

FIG. 3 illustrates an exploded perspective view of cargo pallet 30.Connectors 42 have been omitted from FIG. 3 to improve clarity. Asillustrated in the exemplary embodiment of FIG. 3, pallet base 38 mayhave a shape defined by sides 44, 46, 48, and 50, which may define afootprint of pallet base 38. Sides 44 and 46 may be spaced apart fromeach other and may be disposed opposite each other. Sides 48 and 50 mayalso be spaced apart from each other and may be disposed opposite eachother. Sides 48 and 50 may each connect sides 44 and 46. In oneexemplary embodiment as illustrated in FIG. 3, sides 44 and 46 may bedisposed generally parallel to each other, and sides 48 and 50 may bedisposed generally parallel to each other. In another exemplaryembodiment as illustrated in FIG. 3, in which pallet base 38 may have agenerally rectangular shape, sides 44 and 46 may be disposed generallyperpendicular to sides 48 and 50. Pallet base 38 may also include uppersurface 52 and lower surface 54. As used in this disclosure the term“generally perpendicular” encompasses mechanical structures that areoriented at angles ranging between 90°±1° relative to each other.

FIG. 4 illustrates a magnified fragmentary view of corner 56 formed bysides 44 and 48 of pallet base 38. As illustrated in FIG. 4, each ofsides 44, 46, 48, and 50 may include rail 58. Rail 58 may be disposedalong each of sides 44, 46, 48, and 50. Rail 58 may be generallyU-shaped and may include slot 60 extending along a length of rail 58.Rail 58 may have rail base 62 disposed nearer to lower surface 54 ofpallet base 38 compared to upper surface 52 of pallet base 38. Rail 58may include projections 64 extending from rail base 62 towards uppersurface 52. Projections 64 may be spaced apart from each other and maybe disposed on opposing sides of rail base 62. Each projection 64 mayhave stem portion 66 and ledge 68. Stem portion 66 may extend outwardlyfrom rail base 62 to stem distal end 70. In one exemplary embodiment asillustrated in FIG. 4, stem portion 66 may be disposed generallyperpendicular to rail base 62. Ledges 68 of projections 64 may extendtowards each other from stem distal ends 70. In one exemplary embodimentas illustrated in FIG. 4, ledges 68 may be disposed generallyperpendicular to stem portions 66. It is contemplated, however, that insome exemplary embodiments, ledges 68 may be inclined relative to stemportions 66. As used in this disclosure the term inclined indicates thatan acute angle between two inclined structures may range between about5° and 85°.

Stem portions 66 and ledges 68 may form a generally inverted T-shapedslot 60. Thus, for example, slot 60 may include neck 72 and slot base74, which may be wider than neck 72. Slot base 74 may be disposedbetween rail base 62 and ledges 68. Neck 72 may extend from slot base 74through a thickness of each ledge 68.

As also illustrated in FIG. 4, slot 60 may include openings 76, whichmay be spaced apart from each other. A spacing between openings 76 maybe uniform or non-uniform. Each opening 76 may have a generally circularshape although other shapes are also contemplated. Openings 76 mayextend through a thickness of ledges 68 and may connect with slot base74. It is contemplated that slot 60 and openings 76 may help attachother components (not shown) to pallet base 38 via one or morefasteners. For example, a head (not shown) of a bolt (not shown) may bedisposed in slot base 74 between rail base 62 and ledges 68 so that thebolt may project outward from slot 60 through opening 76. A nut (notshown) may engage with the outwardly projecting bolt to attach othercomponents to pallet base 38. Although only one corner 56 is illustratedin FIG. 4, it is contemplated that corners 56 may also be disposed atthe intersections of sides 44 and 50, sides 46 and 48, and sides 46 and50 of pallet base 38.

Returning to FIG. 3, pallet liner 40 may include pallet liner base 80and one or more pallet extensions 82. In one exemplary embodiment asillustrated in FIG. 3, pallet liner base 80 may have a shape defined bysides 84, 86, 88, and 90. Sides 84, 86, 88, and 90 may define an outerperiphery 92 of pallet liner base 80. Sides 84 and 86 may be spacedapart from each other and may be disposed opposite each other. Sides 88and 90 may also be spaced apart from each other and may be disposedopposite each other. Sides 88 and 90 may each connect sides 84 and 86.In one exemplary embodiment, sides 84 and 86 may be disposed generallyparallel to each other, and sides 88 and 90 may be disposed generallyparallel to each other. In another exemplary embodiment as illustratedin FIG. 3, in which pallet liner base 80 may have a generallyrectangular shape, sides 84 and 86 may be disposed generallyperpendicular to sides 88 and 90. As also illustrated in the exemplaryembodiment of FIG. 3, sides 84, 86, 88, and 90 of pallet liner base 80may be disposed generally parallel to sides 44, 46, 48, and 50,respectively, of pallet base 38. Pallet liner base 80 may also includeliner upper surface 94 and liner lower surface 96, which may be disposedopposite upper surface 52 of pallet base 38. In one exemplary embodimentpallet liner 40 may be disposed on pallet base 38 so that liner lowersurface 96 may abut on upper surface 52 of pallet base 38. A size ofpallet liner base 80 may be about equal to or different from a size ofpallet base 38.

Pallet liner base 80 may include one or more notches 98. As illustratedin the exemplary embodiment of FIG. 3, notches 98 may be disposed alongsides 84 and 86 of pallet liner base 80. A spacing between notches 98may be uniform or non-uniform. It is also contemplated that a number ofnotches 98 along sides 84 and 86 may be equal or unequal. Each notch 98may extend from liner upper surface 94 towards liner lower surface 96.It is contemplated that a depth of notch 98 may be smaller than athickness of pallet liner 40. Thus, for example, as illustrated in FIG.3, notch upper surface 100 may be disposed vertically offset from linerupper surface 94 and may be disposed between liner upper surface 94 andliner lower surface 96. It is contemplated that notches 98 may have asquare, circular, semicircular, elliptical, polygonal, or other shape.In some exemplary embodiments, notches 98 on side 84 may be disposeddirectly opposite notches 98 on side 86. In other exemplary embodiments,notches 98 on side 84 may be disposed in a staggered arrangement betweennotches 98 on side 86. As will be described in detail below, notches 98may allow pallet liner base 80 to be detachably connected to pallet base38 at one or both of opposing and spaced apart sides 44 and 46 of palletbase 38.

As illustrated in the exemplary embodiment of FIG. 3, pallet extensions82 may project outwardly from an outer periphery 92 of pallet liner base80. In some exemplary embodiments, pallet extensions 82 may be fixedlyattached to pallet liner base 80. As illustrated in the exemplaryembodiment of FIG. 3, pallet extensions 82 may be fixed to outerperiphery 92 of pallet liner base 80 at each of sides 88 and 90 ofpallet liner base 80. Each pallet extension 82 may include supportsurface 102, which may support one or more packages. As illustrated inFIG. 3, support surfaces 102 of pallet extensions 82 may be fixed toouter periphery 92 of pallet liner base 80 at sides 88 and 90. Palletextension 82 and support surface 102 may at least in part extendoutwardly beyond a footprint of pallet liner base 80 and also beyond afootprint of the pallet base 38. In one exemplary embodiment asillustrated in FIG. 3, the footprint of pallet liner base 80 may bedefined by sides 84, 86, 88, and 90. As also illustrated in theexemplary embodiment of FIG. 3, pallet extension 82 and support surface102 may be generally inclined relative to pallet liner base 80.

In one exemplary embodiment, pallet extension 82 and support surface 102may be inclined at an angle ranging between about 30° and about 45°relative to pallet liner base 80. The inclination of pallet extension 82may be chosen to conform generally to the shape of a wall of cargo hold10 into which cargo pallet 30 may be loaded. As used in this disclosure,the term about connotes typical manufacturing or machining tolerances.Thus, for example, the term “about 30°” connotes angles ranging between30°±1°. It is contemplated that in some embodiments, pallet extension 82and support surface 102 may be generally co-planar with pallet linerbase 80. As used in this disclosure the term “generally co-planar”encompasses mechanical structures that are oriented at angles rangingbetween 0°±1° relative to each other. In yet other exemplaryembodiments, pallet extension 82 and support surface 102 may be disposedgenerally perpendicular to pallet liner base 80.

In one exemplary embodiment as illustrated in FIG. 3, pallet extension82 and support surface 102 may have a generally rectangular shape. It iscontemplated, however, that pallet extension 82 and support surface 102may have a triangular, polygonal, circular, elliptical, or other shape.Although two pallet extensions 82 disposed opposite to each other andspaced apart from each other are illustrated in FIG. 3, it iscontemplated that in some exemplary embodiments, cargo pallet 30 mayhave only one pallet extension 82 extending outwardly from one of sides88 or 90 of pallet liner base 80. It is also contemplated that in otherexemplary embodiments, cargo pallet 30 may have any number of palletextensions 82 extending outwardly from outer periphery 92 of palletliner base 80.

FIG. 5 illustrates a perspective view of an exemplary connector 42.Connector 42 may include bracket 104 which may be connected to one ormore of openings 76 via one or more fasteners 106. Bracket 104 mayinclude pallet base portion 108 and pallet liner portion 110. Palletbase portion 108 and pallet liner portion 110 may both be planar platelike members. Pallet base portion 108 may be vertically offset relativeto pallet liner portion 110 along a thickness of bracket 104. Palletliner portion 110 may be disposed within notch 98 of pallet liner base80. For example, as illustrated in FIG. 5, lower surface 112 of palletliner portion 110 may abut on notch upper surface 100, such that palletliner base 80 of pallet liner 40 may be slidingly disposed betweenbracket 104 and pallet base 38.

Pallet base portion 108 of bracket 104 may include an opening (notshown) through which fastener 106 may pass to connect bracket 104 withpallet base 38. In one exemplary embodiment as illustrated in FIG. 5,fastener 106 may include bolt 114, which may pass through opening 76 inrail 58 of pallet base 38 and through the opening in pallet base portion108.
